HOLDER FOR PHOTOGRAPHIC MATERIAL.

Specification of Letters Patent.

Application filed August 7, 1914. Serial No. 855,541.

roe and State of New York, have invented certain new and useful Improvements in Holders for Photographic Material; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this s ecification, and to the reference-numerals marked there- My invention relates to cameras or holders for sensitized photographic material adapted particularly for light printing upon the film or sensitized material while in the holder suitable indicia such as names, or other data regarding the exposure made or to be made, and it consists generally in the provision of means whereby designating marks may be formed upon suitable material while in position over the film and then exposed to lightto print the same or a representation thereof through the back of the film all as hereinafter described.

In the drawings: Figure 1 is an enlarged longitudinal sectional view of a portion of the back of a holder or camera embodying my invention; Fig. '2 is a cross sectional view on the line with the outer cover or door closed; Fig. 3 is a similar view showing the cover or door open, the film clamped and the shutter removed for light printing on the film; Fig. at is a longitudinal sectional iew onthe line 3 -;1 of Fig. 3, and Fig. 5 is a plan view of a portion of the shutter covering the film.

Similar reference numerals throughout the several views indicate the same parts.

I have shown my invention applied to a camera or holder of the usual type, in which the film or sensitized medium is passed from one chamber to another across the usual exposure aperture arranged between them, the walls bounding the latter constituting a part of or adapted to be connected with, the rear end of the camera or bellows.

1 indicates the body of the holder and 2 the fiangc formed thereon at the end of the exposure opening. and to which the camera bellows is attached or with which it cooperates as shown.

8 indicates a chamber in which one of the film spools at is supported on suitable cent r d!) a roller at the edge thereof.

6 indicates the usual removable cover for the rear side of the camera or holder and cooperating with the end and side walls to form a light tight joint. Arranged in the rear of the'holder or camera, and in the present instance in the cover (5, is an aperture 7 surrounded by an upwardly extending flange 8 and preferably arranged over the flange 2 which constitutes one endof the opening through which an exposui'e of the film is made in taking pictures. The

aperture '7 is preferably covered by a removable hinged cover plate 9 and extends practically the whole width of the film and is of a size sufficient to permit the inti bduction of the end of a pencil, stylus or crayon so that the operator may write upon material placed beneath the opening, as hereinafter described.

1-0 indicates a shutter 0r septum mounted in the holder andv adapted to be moved beneath or away from the opening 7 in the outer wall of the holder, and in this instance serves both as a means for excluding light and also as a support for the material to be written upon. In the present instance this consists of a metal plate having an operating Patented Oct. 24, 1916.

handle 19 and passing through a slot in the I casing and removable from beneath said aperture when desired, the entrance of light to the interior of the holder being prevented by the excludingflexiblo flaps 11 or other suitable light trap. This slide or platen is, in the construction shown, guided to horizontal movement upon rods or guides 12 secured in the casing and is provided with ears or lugs 13 near the inner end encircling said guides, and the end 14 is somewhat beveled, as shown, to insure the separation of the film and its translucent covering of paper. Arranged beneath the aperture-7 and secured at the sides thereof are spring plates 15 movable toward thefilm and provided on the under side with a covering 16 of velvet or felt, said plates being preferably slit at their edges, as shown, forming a plurality of independently movable fingers 15 and 15 so that when the slide or platen is moved inwardly on its guides beneath them, the different parts or fingers will be lifted successively and the entrance of light to the adjacent portions of the film prevented' The fingers 15 which are beyond the endsof the apertures 7, as shown in Figs. 2- and -3, may "be made to almost meet'each other but the intermediate fingers 15' are shorter and do not project beyond the longitudinal edges of the apertures, as shown in Figs. 1 and 4, as otherwise they .would interfere with the writing implement and obstruct the surface to .be Written upon.

The film cartridgeadapted to be used with this holder embodies the usual transparent film 20, with which is wound a strip '21 of such nature that indicia. may be placed or formed upon it through the aperture '7 by means of a pencil or stylus in the hand of the operator and such indicia caused to be light printed upon the film by light passing through said aperture. This strip 21 may be composed of red or other colored paper or material, a single thickness of which will permit the passage of light of sufiicient actinic value to fog the film, or it may be of white paper or of material having a coating adapted to be displaced by the point of the pencil or stylus and thereby rendered trans lucent on the lines traced thereby, it being sufficient, as before stated, that after the characters or designations are placed upon it, light passing through the aperture will cause the designations to appear in the negative, either as transparent lines on an opaque background or vice versa.

lV'hen the holder or camera is in condition for making exposures in the ordinary way the parts are in the position shown in Fig. 1, the slide 10 beingpushed in beneath the opening 7 and when the operator desires, the door or cover 9 is opened and any desired indicia or designating marks are made upon the strip 21 which, at this time, is supported by the plate 10 and the film is covered by the latter. In order to cause these designations to be light printed upon the film, the plate or septvifun 10 is withdrawn to the position shown in Fig. 3, allowing the spring lingers 15 to move downward or toward the film and press the strip 21 into contact therewith, as shown particularly in Figs. I} and, l. the lingers following behind the plate as it is withdrawn and effectually preventing light entering through the aperture T extending beyond the sides thereof to the film in the casing. The light permitted to pass through the strip 21 to the film causes the designations previously formed upon the strip to be light printed, and as these designations usually appearl'ietween the separate exposu of film they will not in any way interfere with the exposure or negative. As the strip 21. the ends of which form the covering for the cartridge when wound into a roll, is a trille wider than the film, the edge thereof may be placed above the beveled end of the platen as shown in Fig. 3 so that when the latter is moved inward it will readily pass between the film and strip.

Although in the present embodiment I of line with the same and have shown'the septum 10 as movable later- J ally of the direction of the movement of the film, this is not essential, as it could be otherwise arranged though I prefer that at least the'actuating member or a part serving as an indicator be Visible at the exterior of the holder, in order that the position of the septum relative to the aperture 7 be indicated to the operator, that he may not expose the film to light excepting when it is intended to print designations on the film. The external door or cover 9 could be dispensed with if desired, and the septum 1'0 serve as the only light excluding cover for the film.

It will be noted that the septum 10 in the present embodiment, serves as also a table or support for the strip 21 while it is being written upon, which is advantageous in that said strip may, though sufiiciently translucent in single thicknessto permit light printling through it, serve as the outer cover for the film cartridge, a plurality of such thicknesses serving the same purpose as the ends of the ordinary black paper covering for film cartridges and enabling the holder or camera to be loaded in daylight.
